Uzbekistan, the Central Asian country which has had the most dynamic development during the last five years, will celebrate on Wednesday (1 September) the 30th anniversary of its independence from the Soviet Union

Drainage. Disastrous depletion of the flow of the two historic rivers—the Syr Darya and Amu Darya—has brought rapid change in the Aral Sea and greatly altered the delta of the Amu Darya. Most streams of the delta have dried up, and the Aral Sea, once the fourth largest inland body of water in the world, has lost as much as nine-tenths of both its water (volume) and its surface area since 1961. On the north as well as on the east, huge shallow and dead ponds have become separated from the main remnant Aral Sea, cut off by sandbars that emerged as the water level dropped some 45 feet between 1961 and 1992. After 2010 the eastern lobe began alternating between wet periods and dry periods during which it would dry up completely. Overuse of water from the Syr Darya and Amu Darya in both agriculture and industry brought about this dangerous decline. The Syr Darya ceased to deliver any appreciable amount of water to the Aral Sea by about 1978, and flows from the Amu Darya became negligible in the first decade of the 21st century. The southern rivers tributary to the Amu Darya—the Surkhan and Sherabad, followed by the Zeravshan and Kashka—contribute little flow, for the last two trickle into nothing in the desert. The Syr Darya, the second largest river in Uzbekistan, forms there by the confluence of the Naryn and Qoradaryo rivers.
